SPECIFICATION forming part of Letters Patent No. 538,716, dated May 7,1895 Application filed July 13,1894. Serial No. 517,413- (No model.)

The object of my invention is to provide a tinting attachment forprinting presses by which any portion of the paper may be tinted beforeit passes to the impression mechanism whereby matter maybe readilyprinted upon a colored background in a single run of the,

paper through'the press. I accomplish this object by the mechanism shownin the accom panying drawings and hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of a portion of a bed andcylinder press, showing my device attached thereto. Fig. 2 is a planview of the same. Fig. 3 is a side elevation of a portion of aperfecting-press Fig. 4 is a transverse vertical section of the same.Fig.5 is a front View of the cam-wheel for operating the ink-rollers,the upper portion in broken section; Figs. 6, 7, S, and 9 are details tobe hereinafter described.

Referring to the drawings, 1 indicates the frame of the press supportingthe impression cylinder, 2, and a table, 4. 3 are the ordinary black inkrollers. Around the outer edges of the impression cylinder metal bands,12, are secured at both ends in the recesses, 16, in the impressioncylinder by means of suitable bolts, 15, and set screws, 14. Byloosening these set screws the tension upon the bands can be cased, sothat the blocks, 13, having undercut grooves sliding upon the bands maybe adjusted to anypoint desired. This block, 13, fits snugly upon theband and is held in place by the tension upon the band caused bytightening the set screw 14. V

Projecting upwardly from the frame of the press is an arm, 25, fromwhich is carried the inking apparatus, A, consisting of the main roller,8, the distributing rollers, 11, the res ervoir, 26, and the pivotedlever, 7, carrying at one end the transferring roller, 5, and at theother end the small wheel or roller, 6, adapted to be engaged by the camblocks or depressors, 13, as the impression cylinder rotates. A suitablespring connects to the lever, 7, with the frame of the ink apparatus,thereby normally holding the transferring roller, 5, in contact with themain ink roller, 8. Upon the ends of the roller, 8, suitable cams, 10,are provided for engagement with friction rollers, 9, on the frame ofthe inking apparatus, so that a vibratory motion may be given to saidink roller to secure the proper distribution of the ink upon itssurface.

Around the edge of the impression cylinder 11 preferably arrangeascale,s, Fig. 2, for the purpose of more readily adjusting the depressors, 13,in proper relation to the top of the page.

From the foregoing description it will be seen that as the impressioncylinder rotates and the paper is fed around it, the depressor, 13,comes in contact with the roller, 6, and raises the said roller, therebydepressing the transferring roller, 5, until it comes in contact withthe paper upon which it tints a background in length corresponding tothe length of the cam block, 13, and in width corresponding to thelength of the roller, 5. In the further rotation of the impressioncylinder the impression to be taken will be made from the paper and thatportion which has been tinted will appear in the proper place upon thepage or column in contrast to the rest of the paper.

It is to be understood that the transferring roller, 5, may be of anylength desired and that it is not necessary to have the inking apparatusextend the full length of the impression cylinder, for it is obviousthat the frame supporting this apparatus may be of such width as will besufficient to carry rollers of the length desired. The frames supportingthe ink apparatus may in such cases be separate from the main frame ofthe press and suitably bolted or clamped to the arms, 25, as will bereadily understood.

As shown in Fig. 9, the arms, 25, on each side of the press may supporta cross bar, 32, upon which the frame of the inking apparatus is clampedby the jaws, 33, and along which the whole inking apparatus can be slidso as to bring the ink roller, 5, over the proper column or columnsintended to be tinted. In such case the rollers 6, should be supportedupon a shaft extending entirely across the impression cylinder, andsplined or otherwise suitably mounted in the levers, 7, so that thelatter may move longitudinally thereof as the ink mechanism is adjustedto the desired position.

Referring now to Figs. 3 to 8, to adapt my invention to a perfectingpress I mount in the frame above the plate and impression cylinders theshaft, 31, upon which is splined a cam wheel, 17, provided on each sidewith flanges having undercut grooves, 22. A segmental curved plate, 18,having beveled edges is adapted to fit between the flanges of this wheeland is adjustable laterally on the wheel by set screws, 21, which havetheir beveled ends contacting with the beveled edges of the plate. Thisplate is cast with the projections, 19, forming a surface for receivingthe color from the inking apparatus, and it has also, cast upon itssurface, cam projections, 20, which are adapted to operate the rollers,6, for depressing the transferring roller, 5, into contact with theprinting surface, 19, in a similar manner to that described withreference to Fig. 1.

The length of the earns 20, must be equal to the length of the printingsurface at 19, and when two or more tints are to be made the cams, 20,should be staggered as shown in Fig. 6, so that each one will operateits proper roller, 6; and the distance of the printing surface, 19, fromthe respective cams, 20, must of course be equal to the distance betweenthe arcs described by the rollers 5 and 6.

Upon the end of the shaft, 31, is a spur gear, 29, meshing with thegear, 28, on the end of the shaft carrying the impression cylinder, 23.The type cylinder, 24, is provided with a suitable gear, 30, meshingwith the gear, 28, this cylinder being of course out of contact with thecam wheel, 17. When it is desired to tint the paper as it passes aroundthe impression cylinder, the segmental plate, 18, is cast with theprinting surfaces, 19, of the desired length and width thereon, and thecorresponding cams, 20. The plate is then placed around the cam wheel,17, between the flanges and adjusted laterally by the set screws andmoved circumferentially until the printing surfaces are in properrelation in respect to the top of the column, a scale on the surface ofthe cam wheel as shown in Fig. 5, in proper units indicating theposition of the end of the cam plate for the different distances fromthe top of the column. The cam wheel, 17, is laterally movable on theshaft, 31, being secured in position by any suitable means, as by setscrews passing through the hubs. It can thus be moved laterally of theimpression cylinder and placed in position to tint the desired portiontransversely of the page.

The operation of the attachment applied to the perfecting press will bereadily understood from this description, as it is in all respectssimilar to the operation of the device attached to the bed and cylinderpress.

The inking rollers are preferably operated by gears meshing with thegear or circular rack upon the impression cylinder, but they may begiven their rotary motion by any convenient means, as, in presses thatdo not have the rack on the impression cylinder, by fric tion wheels,belt and pulley, or chain and sprocket wheel, &c., all of which is wellunderstood.

I claim as my invention 1. In aprinting p'ress,atinting mechanismconsisting of a rotative part, a color inking apparatus adjacentthereto, a lever fnlcrumed on said apparatus and having an inking rollerjournaled on one arm thereof, normally held out of contact with therotative part, and cams located upon said rotative part, adapted toengage the other arm of the said lever to raise the same and depress thecolor ink roller, at predetermined points, substantially as described.

2. In a printing press, a tinting mechanism for tinting the paper beforeit passesaround the impression cylinder comprising a rotative part, acolor inking apparatus adjacent thereto, a lever fnlcrumed on the ,frameof said apparatus, an inking roller journaled on one arm of said lever,normally held out of con tact with the rotative part, and a cam or camsadjustably mounted upon the rotative part, said cam or cams adapted toraise the other arm of the lever and depress the ink roller, whereby atinted background may be spread upon the paper before it passes aroundthe impression cylinder to the main form, substantially as described.

3. Thecombination withtheimpressioncylinder of a printing press, of aflanged wheel secured to a shaft above and rotating with said cylinder,a segmental curved plate mounted on the wheel and provided with one ormore raised surfaces for receiving ink, and one or more correspondingcam projections thereon, one or more inking apparatus supported aroundthe periphery of said wheel, a lever fnlcrumed on each of said inkingapparatus, an inking roller journaled on one arm of each lever, theother arm of each lever adapted to be raised by its corresponding camprojection on the segmental plate so as to depress the roller intocontact with its corresponding' ink receiving surface, substantially asdescribed.

4. The combination with theimpression cylinder, of the flanged wheellaterally movable upon a shaft journaled above the cylinder, inkingapparatus with levers fnlcrumed thereon, each carrying an inking rollerat one end thereof, normally held away from the wheel, the segmentalcurved plate having bevel edges mounted between the flanges of thewheel, and adjustable laterally and circumferentially of the wheel, saidplate having raised surfaces for receiving ink thereon, and

corresponding cam projections adapted to engage the other end of thelevers to depress the ink rollersas the plate passes under the inkingapparatus, substantially as set forth.

5. In a tinting apparatus, the combination with the impression cylinder,of the flanged ing surfaces corresponding in number to the 15 inkrollers, with corresponding cam projections, adapted to engage the otheropposite ends of the levers, respectively, to depress each roller intocontact with its corresponding ink receiving surface, substantially asdescribed.
